While you wouldn’t have to be quite as restrictive to lose 10 pounds in two weeks, Gans says it would still require an extra level of dedication, and Feller recommends a diet that reduces caloric intake coupled with an exercise regimen that focuses on HIIT, strength training, and cardio. Why? “A lower ratio of carbohydrates and fats and a higher ratio of protein would help preserve lean body mass and promote the breakdown of fat mass,” she says. Your ratios might look something like 50 percent protein, 25 percent fat, and 25 percent carbs, although if you’re working out super hard, says Feller, you could decrease protein to 40 percent and increase your carbs to 35 percent for more easily accessible energy.
There’s one thing to like about visceral fat: It yields fairly easily to aerobic exercise. Vaporizing calories via running, biking, swimming—anything that gets your heart rate up—is an effective way to whittle your middle. In fact, one 2011 study from Duke University Medical Center, published in the American Journal of Physiology, found the sweet spot: Jogging the equivalent of 12 miles a week was even more effective in reducing visceral fat than resistance training three times per week. However, both types of exercise were beneficial when it came to belly fat, the researchers say. (Don’t have time to hit the gym? Try these fun at-home cardio workouts if you’re in a pinch.)
Not much. When you go below 800 calories a day you body says "oh! oh! we need food and there's no food here." So it goes into "starvation mode and keeps all of the fat to sustain life." It uses just the bare minimum to keep your vital organs alive. So, it's not a good way to lose weight and you know you could die. It's a better idea to eat at least 800 calories a day. The smart way to lose weight is to take the number of pounds you want to weigh and multiply that number by ten. Like if you wanted to weigh 125 - you would eat 1250 calories each day.
Conversely, the more food in front of you, the more you’ll eat—regardless of how hungry you are. So instead of using regular dinner plates that range these days from 10 to 14 inches (making them look empty if they’re not heaped with food), serve your main course on salad plates (about 7 to 9 inches wide). Instead of 16-ounce glasses and oversized coffee mugs, return to the old days of 8-ounce glasses and 6-ounce coffee cups.

Eat like a king for breakfast, a prince at lunch, and a pauper for dinner. Ever hear the phrase? It has some truth behind it. Eat early on to jump-start your metabolism and give you enough energy to last comfortably until lunch, and then for dinner begin to wind down and eat the smallest meal of the day. Here are some examples of meals you could cook for yourself during the day, with one snack in between:

The sad truth is that conventional ideas – eat less, run more – do not work long term. Counting calories, exercising for hours every day and trying to ignore your hunger? That’s needless suffering and it wastes your time and precious willpower. It’s weight loss for masochists. Eventually almost everyone gives up. That’s why we have an obesity epidemic. Fortunately there’s a better way.
